PATENT OFFICE JUSTIN '1. ROGERS, OF'SANDUSKY, OHIO, ASSIGNOB TO THE F.WAKEFIELD BRASS 7 COMPANY, OF VERMILLION, OHIO, A CORPORATIONOF OHIOLIGHTING FIXTURE Application flied September 23, 1931. Serial No.564,581.

The present improvements, relating, as indicated, to lighting fixtures,have more particular regard to shields for electric light bulbs wherebyindirect illumination may be secured. One object of the invention is toprovide a. device of this type which, while simple and inexpensive toconstruct, will nevertheless be highly efficient. The device isfurthermore designed as to be capable of application only to a bulb ofthe size intended, thus insuring against the improper combination of thereflecting shield with the wrong size or style of lamp bulb. The deviceis, moreover, so constructed that the shields may be readily stacked ornested together for purpose of storage or shipment.

To the accomplishment of the foregoing and related ends, the invention,then, consists of the means hereinafter fully described and particularlypointed out in the claims, the annexed drawing and the followingdescription setting forth in detail certain mechanism embodying theinvention, such disclosed means constituting, however, but one ofvarious mechanical forms in which the principle of the invention may beused.

In said annexed drawing Fig. 1 is a top plan view of a reflector.

shield embodying the present improvements;

' Fig. 2 is a vertical central section thereof taken on the planeindicated by the line 22-, Fig. 1; Fig. 3 is a broken perspective viewillustrating one of the attaching elements of the shield in twodifferent positions, that of use and when folded or bent out of the wayto facilitate nesting; and Fig. 4 is a section, similar to that of Fig.2, but showing a modification in construction of the shield.

As indicated by the general description of the'device as being oneintended for use in indirectillumination, the shield 1 will be composedeither whole or in part of opaque material, e. g, sheet metal spun orotherwise formed to desired contour; It will be understood that suchcontour may vary, depending upon the ornamental efli'ect desired as wellas the manner in which it is desired to reflect the light from the bulb2, to which the device is designed to be directly attached. The innersurface of the shield will of course be more or less burnished orotherwise finished so as to constitute a reflector. I 7

. ,The preferred means for securing the shield 1 to the lamp bulb 2comprisea plurality of fingers 3 (three such fingers being shown andconstituting the desirable number). These fingers are suitably attachedat points equidistantly spaced about the outer portion of the shield,from which they pro- ]ect upwardly and inwardly,.their inner ends beingso formed as to contact with the upper and inwardly'curved surface ofthe bulb just above the largest diameter thereof. In other Words, thecircle defined by such inner ends, which thus contact with the bulb, isof smaller gizigieter than the maximum diameter of the In use the bulbwill be secured in. a socket forming part of the pendent or other typefixture, whereupon the shield 1 is in turn attached to such bulb bytilting it to one side which will permit the enlarged end of the bulb toenter between two of the fingers 3.

Thereupon the shield is straightened out, i. e.,

aligned with'the axis of thebulb and lowered slightly until thefingerscontact with the bulb in the manner just described. The form anddimensions of the fingers are determined with reference to thereflecting surface of the shield so that the latter will be correctlyspaced and disposed to secure the desired illuminating effect. p

The fingers 3 are preferably made in the form of thinsheet metalstampings that can be bent sidewise substantially into contact withtheinner surface of the shield, as shown in Fig. 3, thus permitting oneshield to be nested inside the other for the. purpose of storage andshipment. Aspreviously indicated, the shield need not be necessarilymade entirely of opaque material, but,as illustrated in Fig. 3, suchshield may compriseian annular portion 4 of opaque material, e. g.,sheet metal as before, with a central portion 5 of glass or other moreorlessrtransluoent material. In thiscase the. device is obviouslyadaptedifor use both in direct and indirect'lighting. i

While the fingers 3 may be made,as1 explain-ed above, so as to belaterally flexible, they should be inflexible in a radial direction soas to preclude application of a shield, designed for use with aparticular standard bulb, from being attached to one of a differentsize. The circle defined by the inner ends of the fingers, moreover,will be of such diameter that while adapting a given shield forattachment to a bulb of the proper size, the fingers will not engage abulb of different dimensions.

Other modes of applying the principle of my invention may be employedinstead of the one explained, change being made as regards the mechanismherein disclosed, provided the means stated by any of the followingclaims or the equivalent of such stated means be employed.

I therefore particularly point out and distinctly claim as myinvention 1. A reflecting shield of bowl-form extended up and outwardlyto guard the light laterally, and means for gauging the size of lamp foruse therewith and for hanging such shield directly to the lamp bulb,said means comprising inwardly-directed lingers spaced below in aproportion relative to the bulbs maximum diameter to pass the bulbwithout being sprung apart and spaced more closely above to engage theglass above its largest diameter.

2. A reflecting shield of bowl-form extended up and outwardly to guardthe light laterally, and means for gauging the size of lamp for usetherewith and for hanging such shield directly to the lamp bulb, saidmeans comprising edgcwise-directed sheet-metal fingers spaced below in aproportion relative to the bulbs maximum diameter to pass the bulbwithout being sprung apart and spaced more closely above to engage theglass above its largest diameter.

3. A reflecting shield of bowl-form extended up and outwardly to guardthe light laterally, means for gauging the size of lamp for usetherewith and for hanging such shield directly to the lamp bulb, saidmeans comprising a plurality of radially-rigid fingers projecting fromthe shield with lower spacing for lateral insertion of the lamp bulb ofrelated size without springing said fingers apart, and in-turned hookends above to seat on the enlarged portion of suc'hbulb.

4. A reflecting shield of bowl-form extended up and outwardly to guardthe light laterally, ai1d means for gauging the size of lamp" for usetherewith and for hanging such shielddirectly to the lamp bulb, saidmeans comprising a plurality of laterally flexible but radiallyinflexible fingers connected to said shield to fold thereagainst fornestshipping and to unfold for use.

5. A reflecting shield of bowl-form extended up and outwardly to guardthe light laterally, and means for gauging the size of JUSTIN T. ROGERS.
